RS-232 Interface Reference Example for LabVIEW FPGA

Overview

This RS-232 example page contains three attachments of code (attachments not described in order of attachment but in order of creation). The original attachment is fpgaserialreadwrite_7.0. It is a simple implementation of a RS-232 interface using LabVIEW FPGA 1.0 (LabVIEW 7.0). It has separate examples for serial reads and for serial writes. This code was updated to the attachment fpgaserialreadwrite_8.2 to incorporate the LabVIEW Project. The latest attachment is fpgaserialreadwrite_8.6. This is an update to the previous two attachments. It adds in features like DMA and IO constants that weren't available in LabVIEW FPGA 1.0. It also combines the previously separate serial read and serial write examples into a single example program.

Would love to use this on my sbRIO-9651 SOM, but get this error, even after porting the code to the SOM from a clean project. I could be this example is old.
Any help is appreciated.

cRIO 9401 rs232 communication

Can any one help me to implement this code with Compact RIO 9068 and NI 9401 DIO module

use with cRIO-9022 and NI-9870
- Jul 15, 2013

By Kamal Joshi, University of Waterloo.

I am trying to transfer this code over to be used with the
cRIO-9022 along with 9118 chassis and NI9870
module. Was anyone able to figure it out since the
earlier comment says that it does not work for this
setup. Any help will be greatly appreciated.

how can I implement this to Compact
RIO with module 9401? any suggestion
will be very appreciated: ]

First, who the heck chose to make the
FPGA_main.vi have a pink icon...? Doesn't
seem to be an NI standard;)
Good documentation and it works well, perhaps
not the best coding style (messy, expansive).
Still this got me up and running as a reference.
Thanks!

What is the maximum baud rate that this
serial port implementation can handle?

Is it possible to add more independents
serial ports in the FPGA?

cRIO has RS-232 port

By Brian Mann, BAE Systems.

CompactRIO has a RS-232 port, I would
imagine you can use the VISA drivers
running on the RT processor to
communicate using RS-232, this would
solve the voltage level problem.

Data Written Indicator
- Mar 14, 2006

hi,
the data written indicator is by default
flase, so how will the data characters be
written into the FPGA memory as the case
will always be flase?...
Any answers
